Digital parametrised ground model in tunnelling - concept and sample application

Abstract: In order to develop a new concept for the future implementation of a digital parametrised ground model in all project phases of tunnel construction to its full extent, the current geotechnical planning process in tunnelling was subject of a basic evaluation. With a sample application, it was possible to show in a first step what can already be done today and valuable experience was gained and furthermore many problems and issues could be identified. In a second step, the Tunnelpixel concept as a possible future solution was developed with the goal in mind to digitise the current, analogue method and the resulting advantages and possible use cases were discussed in further detail.
